摘　　要：为客观评定企业安全绩效,提出一种基于D-S证据理论的企业安全绩效综合评定方法。在确定安全绩效评定指标的基础上,利用模糊函数和群决策方法处理评价过程中的不确定信息,将多源决策信息转换为同一框架下的评价信息,然后根据各决策信息的重要度,通过D-S证据理论的mass函数和证据合成方法对安全绩效评价群决策中的不确定性信息逐层融合。实例表明,该方法能够克服D-S冲突问题,保证企业安全绩效综合评定信息融合结果的准确度,企业安全管理的优劣势的表征更为直观。The objective evaluation system for the Enterprise Safety Performance is improved based on the D-S Evidence Theory.On the basis of a certain index of enterprise safety performance,the uncertain information are dealt with by using fuzzy function and group decision-making method,and the multi-source decision-making information are translated into assessment information in the same framework.According to the weight of decision information,the uncertain information of group decision in safety performance evaluation is interfused reasonably by using mass function and evidence synthesis method of D-S evidence theory.Demonstrations prove that the approach is able to overcome the D-S conflict problem to ensure the accuracy of information fusion,and makes the strengths and weaknesses of enterprise safety management more intuitive.
